Use the law of conservation of momentum. Since the momentum is a linear measure, we can treat each of the dimension separately:
i-direction:

j-direction:

Answer: Final velocity is: (10i + 15j) m/s
Change in the kinetic energy:

Answer: The system lost 500J worth of kinetic energy in the collision
The correct answer is - c. escape.
The word ''escape'' means to get away from something. This word can be used for multiple different situations, and it can refer to both physical and psychological matters.
In a physical sense it can be used to escape from certain unpleasant, or dangerous situation. Example: I have to escape from this prison.
In a psychological sense it can be used to escape, move away, from a certain state of mind. Example: I have to find an escape from my depressive thoughts.

Answer:
v₁ = 3.5 m/s
v₂ = 6.4 m/s
Explanation:
We have the following data:
m₁ = mass of trailing car = 400 kg
m₂ = mass of leading car = 400 kg
u₁ = initial speed of trailing car = 6.4 m/s
u₂ = initial speed of leading car = 3.5 m/s
v₁ = final speed of trailing car = ?
v₂ = final speed of leading car = ?
The final speed of the leading car is given by the following formula:

<u>v₂ = 6.4 m/s</u>
The final speed of the leading car is given by the following formula:

<u>v₁ = 3.5 m/s</u>
Answer: according to the Avagadro's law, volume is directly propotional to no of moles: VXn
according to the Charles law, volume is directly propotional to temperatue: VXT
according to the Boyle's law, volume is inversely propotional to P: VX1/P
when we combine them we get:
VXnT1/P
V=knT/P
k= R(universal gas constant)
V=RnT/P
PV=nRT
